So is there anything you could use these for?
Oxygen-free-copper cabling designed for the audiophool market turned out to be just what you needed to make practical proton precession magnetometers, and the process accidentally removed radioactive impurities so OFC shielding is used in a lot of sensitive particle physics work; there may still be some weird quantum-physics application in which extremely smooth silver cylinders are useful, though you'd feel a bit silly getting this cable and then dissolving the insulation to get to the silver.
